@agent-infra/mcp-server-filesystem NPM

FileSystem MCP Server

A Model Context Protocol (MCP) server that provides filesystem operations.

npm.io

Requirements

Node.js 18 or newer
VS Code, Cursor, Windsurf, Claude Desktop or any other MCP client

Getting started

Local (Stdio)

First, install the Filesystem MCP server with your client. A typical configuration looks like this:

{
  "mcpServers": {
    "filesystem": {
      "command": "npx",
      "args": [
        "@agent-infra/mcp-server-filesystem@latest"
      ]
    }
  }
}

You can also install the Filesystem MCP server using the VS Code CLI:

# For VS Code
code --add-mcp '{"name":"filesystem","command":"npx","args":["@agent-infra/mcp-server-filesystem@latest"]}'

After installation, the Filesystem MCP server will be available for use with your GitHub Copilot agent in VS Code.

Go to Cursor Settings -> MCP -> Add new MCP Server. Name to your liking, use command type with the command npx @agent-infra/mcp-server-filesystem. You can also verify config or add command like arguments via clicking Edit.

{
  "mcpServers": {
    "filesystem": {
      "command": "npx",
      "args": [
        "@agent-infra/mcp-server-filesystem@latest",
        "--allowed-directories /tmp"
      ]
    }
  }
}

Follow Windsuff MCP documentation. Use following configuration:

{
  "mcpServers": {
    "filesystem": {
      "command": "npx",
      "args": [
        "@agent-infra/mcp-server-filesystem@latest",
        "--allowed-directories /tmp"
      ]
    }
  }
}

Follow the MCP install guide, use following configuration:

{
  "mcpServers": {
    "filesystem": {
      "command": "npx",
      "args": [
        "@agent-infra/mcp-server-filesystem@latest",
        "--allowed-directories /tmp"
      ]
    }
  }
}

Remote (SSE / Streamable HTTP)

At the same time, use --port $your_port arg to start the browser mcp can be converted into SSE and Streamable HTTP Server.

# normal run remote mcp server
npx @agent-infra/mcp-server-filesystem --port 8089 --allowed-directories <dir>

You can use one of the two MCP Server remote endpoint:

Streamable HTTP(Recommended): http://127.0.0.1::8089/mcp
SSE: http://127.0.0.1::8089/sse

And then in MCP client config, set the url to the SSE endpoint:

{
  "mcpServers": {
    "filesystem": {
      "url": "http://127.0.0.1::8089/sse"
    }
  }
}

url to the Streamable HTTP:

{
  "mcpServers": {
    "filesystem": {
      "type": "streamable-http", // If there is MCP Client support
      "url": "http://127.0.0.1::8089/mcp"
    }
  }
}

In-memory call

If your MCP Client is developed based on JavaScript / TypeScript, you can directly use in-process calls to avoid requiring your users to install the command-line interface to use Filesystem MCP.

import { Client } from '@modelcontextprotocol/sdk/client/index.js';
import { InMemoryTransport } from '@modelcontextprotocol/sdk/inMemory.js';

// type: module project usage
import { createServer } from '@agent-infra/mcp-server-filesystem';
// commonjs project usage
// const { createServer } = await import('@agent-infra/mcp-server-filesystem')

const client = new Client(
  {
    name: 'test filesystem client',
    version: '1.0',
  },
  {
    capabilities: {},
  },
);

const server = createServer();
const [clientTransport, serverTransport] = InMemoryTransport.createLinkedPair();

await Promise.all([
  client.connect(clientTransport),
  server.connect(serverTransport),
]);

// list tools
const result = await client.listTools();
console.log(result);

// call tool
const toolResult = await client.callTool({
  name: 'list_directory',
  arguments: {
    path: '~/your_computer'
  },
});
console.log(toolResult);
